Real-Time Clock (RTC) is used to track the current time and date. It is generally used in computers, laptops, mobiles, embedded system applications devices, etc.
In many embedded systems, we need to put timestamp while logging data i.e. sensor values, GPS coordinates, etc. For getting a timestamp, we need to use RTC (Real Time Clock).
Some microcontrollers like LPC2148, LPC1768, etc., have on-chip RTC. But in other microcontrollers like PIC, ATmega16/32, they do not have on-chip RTC. So, we should use an external RTC chip
There are different types of ICs used for RTC like DS1307, DS12C887, etc.
